The spotted wing drosophila () is one of the main invasive pests of small fruits in the world. Thus, 19 essential oils (EOs) were selected to analyze the effects through toxicity and repellency on oviposition and adults. In addition, their lethal and sublethal effects on the pupal endoparasitoid were evaluated. The EOs of and spp. had the highest toxicity observed in the topical application bioassay for . In contrast, the EOs of , QT , and showed the highest toxicity in the ingestion bioassay for . The dry residues of and QT reduced the oviposition of . In the repellency bioassays, the 19 EOs analyzed repelled ≅ 90% of the females. All EOs evaluated using the LC values of the products provided mortality of less than 20% of adults and did not cause a reduction in the parasitism of surviving females. We conclude that the EOs evaluated have the potential to be used in the management of . They can also serve as selective active ingredients for the formulation and synthesis of new biopesticides.
实蝇（）是世界上危害小型水果的主要入侵害虫之一。因此，选择了 19 种精油（EOs）来分析其对产卵和成虫的毒性和驱避作用。此外，还评估了它们对蛹期内寄生蜂的致死和亚致死作用。和 spp. 的 EOs 在针对 的涂抹生物测定中表现出最高的毒性。相比之下， 、QT、和 的 EOs 在针对 的摄食生物测定中表现出最高的毒性。 和 QT 的干残余物减少了 的产卵。在驱避生物测定中，分析的 19 种 EOs 驱避了 ≅90%的 雌性成虫。使用产品的 LC 值评估的所有 EOs 导致成虫的死亡率均低于 20%，并且不会降低幸存的 雌性成虫的寄生率。我们得出结论，评估的 EOs 具有在实蝇管理中应用的潜力。它们也可以作为新生物农药的配方和合成的选择性活性成分。
